Ap'plitationfiled March 28, 1921-.

To all whom it may concern Be it known thatI, RoLANnIs A. BLAIR, acitizen of the United States, residing at Fort Wayne, in the county ofAllen and State of Indiana, have invented certain new and usefulImprovements in Rail Anchors, of which the following is a specification.

My invention relates to a rail anchor or anticreeper, and a primaryobject of the invention is to provide a device of this type which willbe light, strong, compact, economical to manufacture and so constructedas to have great holding power against the tendency of the rail tocreep. I

A further object is to provide a rail anchor of-novel construction whichcan be used on. rails of different sizes and having rail bases ofdifferent configuration.

A further object is to provide a rail anchor which, in addition-to thecharacteristics referred to above, will'take a positive hold on the railthat is not dependent upon the creeping stress of the rail so that, ifthe device is provided with an abutment, it will hold the rail againstlongitudinal movement in either direction.

A. further object is to so construct the rail anchor that it may beremoved and replaced repeatedly without impairing its holding power.

The invention consists of the new and improved constructions,arrangements, a-nd devices to be hereinafterdescribed and claimed forcarrying out the above stated. objects and such other incidental objectsas will be referred to in the accompanying description.

The invention is illustrated, in certain preferred embodiments, inthe-accompanying drawings, wherein Fig. 1 is a plan view of one form ofrail anchor made in accordance with my. invention, the anchor beingshownas applied to a rail.

Fig. 2 is a sectionalview on line 2-2 of Fig.v 3 is a fragmentary view,in perspective, of the yoke member of the anchor.

Fig. 4 is a view, similar to Fig. 1, showing a modification.

Fig. 5 is a fragmentary View, similar to Fig. 2, showing anothermodification.

Fig. 6 is a detail view, in side elevation, illustrating the form of keyemployed in the anchor illustrated in Fig. 5, and

Serial No. 456,396

Fig. 7 is a View illustrating a different form of key.

Like characters of reference designate like parts in the several figuresof the drawings. Referringfirst to Figs. 1, 2, and 3, 1O designates arailway railand 11 one of the ties supporting the rail. The rail anchor,as shown in these figures, consists of a yoke member 12' and a key 13,the latter being preferably tapered or wedge-shaped. The yoke 12is'made, preferably, of a relatively high carbon steel so as to beresilient. It may be formed by cutting and bending a piece or blank ofsheet steel. The yoke member consists of a bar 14 to extend under thebase 15 of rail 10, a foot or tie abutting flange 16, andhooks or jawforming portions 17 and 18 made by bendingover the endsof the bar 14.The lipof jaw 18 is longer than that of jaw 17. The jaws are formed withopenings 19 and 20 for the key 13 which, as shown in Fig. 2, is driventhrough openings 19 and 20 between the bottom of rail base 15 and thebar 14C of the yoke member. The key 13 is'preferably made of relativelysoft steel so as to be tough and unbreakable, but this is not essential.The openings 19 and 20 are preferably arranged in a diagonal line sothat the key 13 stands obliquely to the rail. The purpose of this is tocheck the tendency of the yoke to rock on the key.

The jaws 17 and 18 are preferably formed so that they are bent when thekey" 13 is driven home. The dotted lines in Fig. 2 indicate,approximately, the original contour of the aws, the full lines showingthe strained contour thereof when the yoke is under the wedging pressureof the key.

In Fig. 1 I haveshown a rail anchor like that shown in theprecedingthree figures except that the openings 19 20 are disposed sothatthe keyis parallel to the tie.

In Figs. 5 and 6 the yoke 12 may, be formed either like. the yoke 12 ofFigs. land 2 or the yoke 12 of Fig. 4:. The key. 13 is given a twistingset, the key, in this case being of relatively high carbon steel. Whenthe key is driven in between the rail base and the yoke the twist isstraightened to a greater or less extent, creating a strain which makesthe key self-locking.

A similar-resu-ltmay be obtained bygiving the key a bend as shown inFig. 7 the key in this figure being designated 13.

It will be seen that the holding power of a rail anchor constructed asabove described will be very great in proportion to its size and weight.The device has a resilient en gagement with the rail so that its holdthereon is not easily afiected by vibration or other disturbinginfluences. The key has a very gradual taper with consequently littleten dency to back out from the position to which it is driven. The lipsof jaws 17, 18 are strained when the wedge is driven home. The device iseasily applied to a rail by first hooking the jaw 18 over the rail base,raising the yoke and moving it laterally (to the left, Fig. 2) until jaw17 is engaged with the other edge of the rail base, then driving in thekey 13 (or 13 or 13, as the case may be). The device is as easilyremoved from the rail by driving the key from its small end. The anchormay be used repeatedly without detrimentally affecting its holdingpower. The same anchor may be used on rails of different sizes andsomewhat different cross sectional configurations. For rails beyond thelimit of adjustment of any given key the device may be adapted withoutchange in the yoke by merely using a wider or narrower key. The yokestands at some distance below the bottom of the rail base, particularlyat the right hand end (Fig. 2) so that the tie abutting flange 16 doesnot have to be very long in order to obtain a firm bearing on the tieeven when the latter is of the hewn type. Assuming an abutment for theflange 16 on both sides thereof, for example, when imbedded in theballast the anchor will prevent rail creep in either direction.
